ROD-GUIDE FOR LOOMS.

SPECIFICATION forming part of Letters Patent No. 723,903, dated March 31, 1903.

Application filed August 26, 1902. Serial No. 121,079. (No model.)

To all whom, it may concern.-

Be it known that I, DANIEL O. NORCROSS, a citizen of the United States, residing at North Billerica, county'of Middlesex, State of Massaparallel with the race of the lay and connecting opposite shifting shuttle boxes with a guide for said connectingerod, whereby accuracy in the position of the rod maybe better secured. The more accurate the position of the connecting-rod the more accurate its movements and the greater the accuracy in placing the shuttle-boxes in exact position with relation to the race of the lay, and consequently the more perfect the Weaving. Further, by guiding the connecting-rod as herein provided for the durability of the loom is increased and the wear on the operating parts is reduced.

Figure 1, in front elevation, shows a sufti cient portion of aloom with myimprovements added to enable my invention to be understood. Fig. 2 is anenlarged detail showing part of the lay with'my novel box-rod guide applied; and Fig. 3 is a detail in the dotted line (1:, Fig, 2.

The loom-frame A, the rocking shaft A, carrying the lay B, the shifting shuttle-boxes B B carried by shuttle-box rods 0 O, the pulleys 2, 3, 4, and 5, sustaining the flexible cords or connections a a, the connecting-rod a joined at one end with the cord at and at its other end with cord a extended over pulley 6 and connected with shuttle-box rod 0, are and may be all as common in the socalled Knowles loom, and in practice the cords a a are pulled in the proper time and order through the requirements of a patternsurface of usual construction, as one or another cell of one or the other shuttle-box is to be put in position opposite the run of the lay.

In accordance with my invention I have provided a novel guide for the rod a Whereby its exact position with relation to the lay and the sheaves 5 6 may be gained. I have provided the under side of the lay with a guide D, shown as comprising a main stand The roller as herein shown is represented as grooved at its periphery to receive, sustain, and guide the connecting-rod a A cotter pin 2 is shown as crossing the rod a above the roller.

It will be understood that the main stand may be adjusted on the lay to place the rod 6& exactly in line with the grooved peripheries of the rollers 5 and 6, and by adjusting the portion dvertically on the main stand the roller may be so positioned as to sustain the weight of the rod a and secure for it the best possible position to insure accuracy of movement of the box B The roller prevents wear on the rod a and by grooving the roller to receive the rod forward and backward sway= ing of the rod is obviated.

As stated, a loom provided with the guide shown will weave more perfect cloth than would a loom'in which the guide was of but one piece and non-adjustable.

, I am not aware that a loom having a connecting-rod such as a has ever been sustained or guided by a roller.

My invention is applicable to any loom hav= ing a cross connecting-rod, and when so applied any lateral vibration of the rod, due to the rapid reciprocations of the lay in its movements of beat up, is entirely overcome.

Having described my invention, What I claim as new, and desire to secure by Letters Patent of the United States, is-

1. In a loom, alay, shuttle-boxes at opposite ends thereof, a connecting-rod occupying a position substantially parallel with the race of the lay, and a guide for said rod to prevent lateral or side vibrations due to movements of the lay, said guide comprising a stand connected with the lay and having a roller to guide said rod.

2. In a loom, a lay, a connecting-rod guide,

5. In a 100m, a lay, a connecting-rod guide,

comprising a main stand, an adjustable por- 15 tion carried thereby and having a roller grooved at its exterior to receive, sustain and guide said rod.

In testimony whereof I have signed my name to this specification in the presence of 20 two subscribing Witnesses.

DANIEL C. NORCROSS.
